Sizing Horsepower for a Lombok-Built Boat: Hull Weight, Load and Cruise Speed
Sizing horsepower for a Lombok-built boat starts from three numbers: the boat’s loaded displacement, the speed the schedule genuinely requires, […]
Materials & Engineering
Hull material is the first irreversible decision in a new build, and it sets maintenance cost for the life of the vessel. Timber, fibreglass, aluminium and steel each behave differently in warm tropical water, and each is repairable to a different standard in eastern Indonesia. This track works through that choice honestly: density and rot resistance of ulin, bengkirai and teak; laminate schedules and where fibreglass earns its weight; where aluminium is worth the premium and where it is not; and what a steel hull really costs to keep. Beyond the shell, it covers propulsion — outboards against inboard diesels for passenger work, fuel burn per crossing, spares availability in Lombok, and the annual maintenance load owners underestimate. Engineering decisions made here are what a surveyor will measure years from now.
Marine Plywood vs Solid Timber in Lombok Boatbuilding: Where Each Belongs
Marine plywood and solid timber both belong in Lombok boatbuilding, but not in the same places. Solid hardwood — ulin,
